I realise the GDPR has a personal use exception, but as far as I can tell one can't safely assume it applies to a blog on work-related topics, especially if it earns any kind of income (https://law.stackexchange.com/questions/28070/would-gdpr-affect-my-own-personal-website).
What does this comment have to do with your post?
The easiest fix would be for these companies to comply with the law and respect their users' privacy. That's what the law demands of them.
I write a blog in my spare time. For the reasons stated above, I believe it needs to be GDPR compliant, but I don't really have the time or knowledge to comply -- so I've been seriously considering geo-blocking EU residents.
If you know of an easier way to comply with the law, respect my user's privacy, and still serve the site to EU residents, I'm eager to hear it.
